About Me

I’m Cassia, a web developer with a passion for building modern, bespoke websites that are fast, responsive, and user-focused. I specialize in WordPress, JavaScript, PHP, React, and Python blending design and functionality to create seamless digital experiences.

Whether it’s developing a custom theme, building a full-stack web app, or automating a process with Python, I love crafting solutions that are both elegant and effective. I’m always eager to learn new technologies and take on challenging projects that push me to grow.
